Description of the Invention: [Technical Field] The present invention relates to a method and apparatus for searching for data, and more particularly to a method and apparatus for searching for content containing a content of a delimiter. ^ [Prior Art] Advances in technology and processes have enriched the functionality of many digital or electronic devices, while making them lighter and lighter, making it easy for users to carry around. For example, portable devices such as cell phones or personal digital assistants (PDAs) play a very important role in the daily lives or work of many people. To facilitate the use of life or work, users will probably store a lot of information on their mobile phones or PDAs, such as the name, address, email address, e-mail number, or regular Liu of a friend, family member or customer. View the URL and more. When the user wants to find one or more pieces of data from a lot of data stored in the mobile phone or PDA, the method of driving knows to use the selection key (selecti〇n kiss) to gradually filter the data. - However, 'the search efficiency is not ideal' is when the amount of data is considerable. Another conventional method is to input the first few words of the data to be searched by the user in order, and the system and the system are input according to the user. The meta-sequences are filtered out in order to match the data of 1341990. For example, when the user enters a character "a", the system will filter all the data starting with the character "a" from the database or memory unit. If the user then enters a character "s", the system will further filter out the second character "s" from the data beginning with the character "a". Then, if the user enters a character, U,,, the system will select the third character as the data of ,, u, from all the data beginning with the string, AS", and so on. As the number of characters entered by the user increases, the data that conforms to the rule will be gradually reduced. Finally, the user can find the desired data from a small number of data that matches the input string. However, in space saving Considering that the control or input interface on devices such as mobile phones or pDAs is usually very simple, it does not set many buttons like the keyboard of a computer, so users can only use the limited buttons to input the beginning words of the data to be searched. It is obvious that this data search method is not convenient in practical application. As can be seen from the above φ, the conventional data search method still has much room for improvement in terms of ease of use and data search efficiency.

[Embodiment] • Generally, many data stored by a user in a portable device such as a mobile phone or a PDA are composed of English letters, double digits (d〇uWe_bytecharacter), numbers, or punctuation marks. A string of characters, such as a friend, family member, or customer's name, address, e-mail address, phone number, 'or URL of a frequent repertoire, and so on. One of the characteristics of these string data is that it usually contains at least one delimiter, such as: -, @, ·, , , spaces or other punctuation. For convenience of explanation, in the following embodiments, all characters except letters, double-bit words, and numbers are classified as interval symbols. For example, in 1341990, the e-mail address "email@test.com" has two separate symbols: "@" and "." and there are 6 in the "http://www.uspto.gov/" website. Separation symbols: 1 ":", 3 "/" and 2 ".". Please refer to FIG. 1, which is a block diagram of a data search device 100 in accordance with a preferred embodiment of the present invention. As shown in the figure, the data search device package Φ of the present embodiment includes a delimiter definition unit 110, a remaining unit 120, and a search module 130. The operation and implementation of the functional blocks of the data search device 100 will be further explained below. The section symbol definition unit 110 is used to define a character attributed to the section symbol. As described above, in the present embodiment, all characters except letters, double-bit words, and numbers are classified as interval symbols. Please note that in practical applications, the φ content setting of the interval symbol can be adjusted according to the needs of the system design, and is not limited to the foregoing embodiment. In practice, the segmentation symbol definition unit U can be implemented in a hardware or software manner.

In the present embodiment, the search module 丨30, for example, the processor inputs a sequence of values from one of the input modules (not shown), from the plurality of data stored in the storage unit 丨20. , selecting at least one target data corresponding to the sequence of input values. The input module may vary in the actual application depending on the type of data search device (8) 1341990. For example, if the data search device 1 is a mobile phone, the input module is usually a key pad on the mobile phone. If the data search device is - PDA, the input module may be the touch panel on the PDA (_h P_) H staff can also lack other interfaces for the guzzler input data 'for example, keyboard, handwriting The input panel, or the user can control the sound-sensing module material of the data search device KK) through sound. As shown in the figure, a buffer 140 is typically provided between the search module 130 and the input module for buffering the sequence of input values from the input module. In practical applications, the format of the input sequence derived from the input module may vary with the size of the input module. For example, if the input module is a - touch panel, the value of the input value is the same as the value of the input value, and the input module is a single-sub-group. Then each input value of the round-robin value sequence may correspond to more than one character. For example, the button "2" in the button module of the mobile phone represents the characters "a", "b" and "c", and the button, 7" represents the sub-elements p", q", "r" and "s" "." In this type of application Yin, the data search device, set 1 will also set the - character index unit (character 丨 ndexunit) 5 〇, used to record at least one character corresponding to each input value. When the search module 13 receives an input value, the round-robin value can be converted into at least one corresponding character according to the content recorded in the character index unit 15A. 1341990 Next, please refer to FIG. 2, which is a flow chart 200 of an embodiment of a data search method of the present invention. The operation of the search module 130 will be further explained below in conjunction with the flowchart. For convenience of explanation, it is assumed here that the data search device 1 is a mobile phone, and it is assumed that the storage unit 120 stores a commonly used bookmark list 300 as shown in Fig. 3, which contains nine pieces of web address data. In step 210, the search module 130 receives a sequence of input values from the input module that contains one of the K input values through the buffer 14. In step 220, the search module 13 ' selects the first character (ie, the first character) of the preceding data segment from the common URL column & 300 stored in the storage unit 12, respectively. Information on the input values. Further, since the data search device 1GG in the present embodiment is a mobile phone, the search module 130 in step 22, according to the contents of the character index unit 15 Converted to (4) at least one target word 疋 'and from the list of commonly used URLs _ out of the beginning of the data segment at least the corresponding target character of the data segment at least - the target data. It should be noted that the implementation steps of the foregoing steps 21A and 22B are only one embodiment, and do not limit the actual operation mode of the present invention. 1341990, in the preferred embodiment, steps 210 and 220 are performed simultaneously. For example, when the first input value of the input value sequence received by the search module is "9", the search module 130 will input the _th input value according to the content of the character index unit 15(). "9" is converted into the corresponding at least - target-target character. In the present embodiment, the characters corresponding to the first input value "9" have "w", "x", "y", and "z". Therefore, the search module 130 will filter out the data of the first data segment whose first character is "w", "x", "y" or "ζ" from the list of commonly used URLs stored in the storage unit. . After the comparison, the search module 13 will find six candidate websites: "www.abc-xyz.org", "www.cnet.c〇m", "Cong 3 dsch〇〇Udu", "www.hospital.org", "www.k_bankc〇m" and "yah〇〇c〇m". If the search module 130 receives the next input value as "2", the search module group 130 queries the character corresponding to the input value "2" from the character index unit 〇5〇, and obtains The result will be the characters "a", "b" and "c". Then, the search module 筛选3〇 will filter the data of the second data segment from the candidate URLs to the character J "a", "b" or "c". The results of the screening will result in three URLs: "www.abc-xyz.org", "www.cnet.com" and "yahoo.com". These 3 URLs will be used as candidate URLs for the next search. Assuming that the next input value received by the search module 130 is also "2", the search module 8 13 1341990 group 130 will be from the candidate URL obtained from the top-back search! The information at the beginning of the third data segment is selected as "a", "b" or "e". In the present embodiment, the search module 13G finally obtains the website address "Nayi". In other words, in the actual example, the user simply presses the button on the mobile phone in sequence, and the search module 130 searches for the corresponding URL from the common website. Γ www.cnet.com j ° _#Materials to find, when _ _ _ _ _ _ _: list 300 to find the URL "g (10) ps.msnxGmW /" of the word (four) correction, just press '- can be followed. For the work, the _ group _ _ search for the resulting. It is temporarily stored in the buffer or memory stack for the search module to be used as the search target when comparing the bar to the bar. The result of each search by the search module (10) can also be displayed on a display screen (not shown), so that the user can select the desired data from the candidate data by using the selection key.
